Subject: DDD LLC - Phase 2
After reviewing the latest preliminary grading, erosion control, drainage and utility plan dated 7120102, and after reviewing
the site, I have the following comments /recommendations:
The site plan relative to building location and parking lot Layout is acceptable as submitted. The proposed parking
configuration in the central parking area between the buildings has been modified from the previous layout, but the stalls
and aisle widths meet or exceed minimum widths.
The plan calls for rock construction entrances at both existing paved driveways to the site, one off 55th Street N.
and one off Memorial Avenue N. Since it is highly doubtful they will install these rock entrances on top of the existing
bituminous, a rock construction entrance should be shown at the location equipment will actually be entering /exiting the
non -paved area.
'
We recommend more erosion control measures downstream of the proposed curb cut location. A rip rap swale
with geotext le fabric is proposed, but due to the erosion occurring at other similar locations on Phase 1, we recommend
some type of ditch protection (wood fiber blanket, etc.) from the end of the rip rap to the east end of the property with ditch
blocking (hay bales, silt fencing, etc.) at the east end.
Following are some issues relative to Phase 1 observed while reviewing the site:
Erosion is occurring at a number of 'locations; 1) the storm sewer entrance in the southwest corner of the pond, 2)
the rip rap overflow from the parking lot to the pond, 3) the slope from the northerly corner of the trash enclosure to the
pond, and 4) the easterly end of the culvert under the southerly driveway onto 55th Street N. These locations should be
restored, and corrective measures taken to prevent further erosion.
The plan should more accurately depict the existing improvements constructed with Phase 1.
The easterly edge of the existing bituminous parking area should be shown.
The trash enclosure and adjacent curb and gutter have been slightly modified from this drawing.
A large electrical box sits east of the trash enclosure.
The existing catch basin in the central parking area has a 12" inlet from the east -- what is this going to serve?
Additionally, the storm sewer appears to be HDPE, not RCP as shown on the plan.
A gate valve is located approximately at the end of the water main constructed in Phase 1.
I was not able to locate the existing sanitary sewer cleanout shown on the plans.
